101 / Understanding eviction data / with Juan Pablo Garnham
Thu Feb 05 2026
Juan Pablo Garnham — Communications and Policy Engagement Manager at the Princeton Eviction Lab — is in good traffic this week for a conversation about the hidden scale of America's eviction crisis and why the data didn't exist until recently. Before 2018, there was no way to answer a simple question: how many evictions happen in the United States each year? The lab, founded by Matthew Desmond after winning the Pulitzer Prize for Evicted, set out to change that — and in doing so, revealed eviction not as a symptom of poverty, but as a cause of it.
Juan Pablo walks through the lab's two core offerings: the National Eviction Map, which tracks every county from 2000 to 2018, and the Eviction Tracking System, which monitors over 30 cities and ten states month by month since the pandemic began. He explains why collecting this data remains extraordinarily difficult — most states don't mandate reporting, courts lack technology or willingness to share records — and how the lab works with journalists, policymakers, and advocates to turn raw numbers into impact.
The research is clear: Black and Latino families face eviction at rates several times higher than white families, mothers with young kids are especially vulnerable, and one eviction can trigger a cascade of financial and health consequences that become nearly impossible to escape.
We also touch on: Why eviction data matters for housing policy. How teachers often see the warning signs first. The domino effect of a single financial shock. Car dependency as a hidden eviction risk. Illegal lockouts and 911 call data. Why Portland, New York, and Santiago all taught him something about commuting. What it takes to make technical research accessible and actionable.
